Funding entity World Bank

The objective is to develop the Spanish case study on the integration of RES in power systems.

Research topics:
• Steady-state: Load flows, analysis of power system constraints, optimal load flows, voltage control ancilliary service,short-circuits, protections in transmission and ditribution networks
• Automatic generation control: Design and tuning of AGC regulators, identification of power plant models, primary and secondary regulation ancilliary services
• Stability: Large disturbance stability, tuning of frequency loadshedding schemes, excitation control, small disturbance stability, tuning of power system stabilizers, identification of AVR and governor models
• Green energy integration
• Energy markets design and regulation
• Network regulation and tariff design with large shares of DER
